✨ Text Case Conversion Types Explained

UPPERCASE

Converts all letters to capital letters. Useful for headings, emphasis, or creating attention-grabbing text.

Example: hello world → HELLO WORLD

lowercase

Converts all letters to small letters. Useful for normalizing text or creating uniform formatting.

Example: Hello WORLD → hello world

Title Case

Capitalizes the first letter of each major word. Perfect for titles, headings, and proper formatting of names.

Example: the quick brown fox → The Quick Brown Fox

Sentence case

Capitalizes only the first letter of each sentence. Standard formatting for paragraphs and regular text.

Example: hello world. this is a test. → Hello world. This is a test.

Capitalize Each Word

Capitalizes the first letter of every single word, including articles and prepositions.

Example: the cat in the hat → The Cat In The Hat

camelCase

Removes spaces and capitalizes the first letter of each word except the first. Common in programming for variable names.

Example: hello world test → helloWorldTest

snake_case

Replaces spaces with underscores and converts to lowercase. Popular in Python and database naming conventions.

Example: Hello World Test → hello_world_test

kebab-case

Replaces spaces with hyphens and converts to lowercase. Used in URLs, CSS class names, and file names.

Example: Hello World Test → hello-world-test

CONSTANT_CASE

Converts to uppercase with underscores replacing spaces. Used for constants in programming.

Example: max buffer size → MAX_BUFFER_SIZE
